Everything was fine, no changes, no updates,, shut off computer, next time boot up second monitor shows bios screen, shows first level windows loading screen, once it gets to second level windows screen and desktop, no more second monitor. not detected in devices and printers. running intel onboard graphics thru I5-2500k CPU and updated to latest driver
without effect. Its not a cable problem because the monitor shows the BIOS screen and initial windows screen. Any thoughts?
